Two hundred and two strains of prompt lactose‐fermenting enterobacteria were examined, using 12 biochemical tests. In addition the susceptibility to several antibiotics was recorded. Identification on the basis of H 2 S production, ornithine decarboxylase activity, motility and citrate utilization (HOMoC) was compared with the results obtained using the classical IMV iC tests: indol, methyl red, Voges‐Proskauer and citrate. Only the former set of reactions seemed suitable for clear‐cut identification of the 4 genera Escherichia, Citrobacter, Enterobacter and Klebsiella. In showing low sensitivity to cephalotin Citrobacter and Enterobacter seemed to differ from the other 2 genera, and this could be used as an additional criterion for their identification.
